General
1.1
The third meeting of ITU-T Study Group 19 “Mobile Telecommunication Networks” in the
2005-2008 study period, took place in Geneva, Switzerland, in the ITU Facilities from 5-9
September 2005. The meeting was convened by TSB Collective Letter 3/19 dated 3 June 2005 and
was chaired by Mr John Visser (Nortel, Canada), assisted by the following SG 19 Vice-Chairmen:

Mr Maurice Ghazal (MPT, Lebanon)

Mr Motoshi Tamura (NTT DoCoMo, Japan)
1.2
Two Vice-Chairmen were not able to participate in this meeting, extended apologies for
their absence, and designated representatives to take their places:

Mr Young Kyun Kim (Samsung Electronics, Korea) represented by Mr Kees den Hollander

Mr Patrick Masambu (Communications Commission, Uganda), represented by Mr Patrick
Mwesigwa
1.3
Three Vice-Chairmen were not able to participate in this meeting and extended apologies
for their absence:

Mr Kiritkumar Lathia (Siemens Mobile Communications, Italy)

Mr Bruno Ramos (ANATEL, Brazil)

Mr Konstantin Trofimov (NIIR, Russia)
1.4
The Chairman opened the meeting at 09:30 on 5 September 2005 and welcomed the
participants. The Chairman invited Dr Houlin Zhao, ITU TSB Director, to provide some opening
remarks. Dr Zhao gave a warm welcome to the delegates, and then noted a number of points:

The GSC-10 meeting which took place in Sofia Antipolis, 28 August - 2 September
produced a Resolution on IMT-2000 and beyond1 which explicitly recognized the role of
ITU-T SG 19 in studying systems beyond IMT-2000.

Three study groups meeting in parallel per the discussions at WTSA-2004 provide a good
opportunity for experts to come together to advance the work on Next Generation
Networks. A new name for this collective effort is being sought. Co-located Rapporteurs’
meetings addressing NGN matters will be announced by Collective Letter to raise the
profile of these meetings. The Chairmen of Study Groups 12 and 16 have indicated
willingness to have relevant Rapporteurs’ meetings from their Study Groups co-located and
included in these Collective Letters. The overall goal is to maintain the momentum of the
NGN work as it transitions into the regular Study Group structure. The TSB is planning to
publish a “book” of the FG NGN output documents to capture in one place what has been
achieved, and what is planned. These and other methods are aimed at dispelling any
misperception that the work will be slowing down as a result of this transition.

An issue is noted on the SG 19 agenda with respect to continuing the NG studies on fixedmobile convergence and mobility. It is natural that SG 19 should take care of this. He noted
that SG 19 is working quite well although it is not that big: major companies are still active
and experts from companies are able to work calmly.

He encouraged more attention be paid to case studies to show examples and principles of
the application and evolution of IMT-2000 networks, in conjunction with the BDT as
1
This Resolution is included in the report of GSC-10 provided in TD 231.
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC
-4COM 19 – R 3 PUBLIC – E
appropriate, noting that Africa and India, as two examples, are experiencing very high
growth rates in mobile subscriptions. He noted that not only mobile but also fixed-mobile
convergence will have significant economic and social effects on the world.
1.5
The SG 19 Chairman provided his opening remarks and stated his overall objectives for the
meeting. These are summarized here:

SG 19 should discuss its situation and should decide to assert its mandate per WTSA-2004.

In order to put some substance behind asserting its mandate, SG 19 should be prepared, at
this meeting, to conduct a thorough review of all FG NGN draft output documents that
contain mobility or fixed-mobile convergence material, and should provide detailed and
specific comments as feedback to the next meeting of the FG NGN in November.

Draft new Recommendation Q.1741.4 should be finalized and offered to the closing
plenary for Consent.

All deliverables identified in the Work Programme should be progressed as much as
possible in accordance with input material available.
2.
Documentation for the meeting
2.1
The agenda, as provided in Collective Letter 3/19, is available as TD 177 and has been
attached to this report as Annex 1. It was accepted as proposed.
2.2
The meeting considered twelve contributions (D-17 through D-28.) The meeting considered
fourteen liaison statements, listed in TD 198R3. One series of Temporary Documents was assigned.
A proposed document allocation was made available as TD 210. TDs generated during the meeting
are not included in this allocation.
2.3
The list of participants was distributed as TD 242.
2.4
All documents for the meeting may be downloaded from the SG 19 web page:

Approval of Draft Recommendation
3.1
AAP Consent of Draft New Recommendation
3.1.1 A draft new Recommendation entitled “IMT 2000 References to Release 6 of GSM evolved
UMTS Core Network” was proposed for AAP Consent at the closing plenary. It was confirmed that
the requirements of Recommendation A.5 with respect to referencing documents of external
organizations were met: details are found in §6.2 of TD 230R1. A question to the plenary on patent
information related to the candidate draft Recommendation elicited no response. TD 222 lists
editorial work required to complete preparation of the draft new Recommendation for the AAP
process. The following Recommendation has therefore been consented for AAP. The Q-series
number allocated to this Recommendation is Q.1741.4.

3.2
Translation of Text of New Recommendation
3.2.1 The meeting considered the matter of how best to translate the text of newly AAP
Consented Recommendation to ensure that the results would be useful and meaningful to those
using other language versions while minimizing the amount of translation effort required. SG 19
recommends that the entire contents of Recommendations in the Q.174x.y series should be
translated with the following exceptions:
•
Translation of the titles of references that exist in English only should not be done.
•
Translation of the tables should not be done.
•
Translation of the list of acronyms and abbreviations should be handled in a special way.
Since acronyms and abbreviations often do not translate well, all language versions should
include both the English as well as the translated list of acronyms and abbreviations in
order to provide a common reference point for all readers.
3.2.2 It is estimated that the above approach may save some of the translation effort that would
otherwise be required with no loss of value to the users of these Recommendations. It is suggested
to the TSB that it considers proceeding accordingly.
4
Next Generation Networks and SG 19’s Role
4.1
The report and selected draft output documents of the seventh meeting of the Next
Generation Networks Focus Group (Beijing, China, 27 June – 1 July 2005) are found in TD 188 and
TD 189. The list of meeting report documents and current output documents for the eighth meeting
of the FG NGN (Geneva, 24 August - 2 September 2005) was provided in TD 213. The report of
the eighth meeting and the draft output document “NGN Release 1 – Scope” are found in TD 215.
4.2
The meeting discussed the need for SG 19 to assert its position on its role in NGN studies,
especially with respect to mobility and fixed-mobile convergence. TD 211 provides a “Proposed
statement on SG 19's role in NGN studies” drafted by the SG 19 Management Team. This statement
was endorsed as proposed (the UK expressed a reservation) for input to the NGN-JCA meeting on 6
September where it is available as JCA document 13. This statement is attached as Annex 3.
4.3
The summary report of the JCA is available as TD 239 and reflects essential points from
the SG 19 position statement.
4.4
Three contributions from Canada, D 24, D 25 and D 26 indicated the necessity for SG 19 to
review the FG NGN deliverables to identify mobility and fixed-mobile convergence documents, or
sections thereof, to conduct a thorough review, and to provide feedback to the FG NGN
accordingly. The meeting agreed that the indicated Rapporteurs be instructed to do this.
5.
Reports of Interim and Related Activities
5.1
TD 199 provides the report of the Q.2/19 e-meeting of 14 – 22 June 2005. TD 200 provides
the report of the Q.2/19 e-meeting of 4 – 11 July 2005. The results of these e-meetings will be used
as input to the discussions under Q.2/19 at this meeting. The planned Q.1/19 e-meeting was
cancelled due to insufficient input documents. The Q.5/19 e-meeting was brought to a close part
way through due to lack of interaction on the electronic forum.
5.2
One liaison statement had been reviewed and approved by correspondence since the last SG
19 meeting, and was endorsed:

TD 183 is a liaison statement sent to ITU-R WP 8F “Executive summary on 2nd ITU-T SG
19 meeting (Geneva, 3 – 6 May 2005)” to provide information per the title.

5.3
Notes on the discussions on the remaining general documents identified in the opening
plenary may be found in Annex 2.
5.4
Open Access to SG 19 Documentation
5.4.1 The SG 19 Chairman is to report to TSAG on SG 19’s experience to date with respect to
the conduct of a trial of making SG 19 documents publicly accessible. It is noted that three
contributions and a number of TDs to this meeting were designated for public access. A public
version of the previous meeting’s formal report has also been available for some time, together with
a number of Rapporteurs’ meeting reports.
5.4.2 No issues or concerns of any sort have arisen as a result of the open and public access to
these documents to date. The SG 19 Chairman will so indicate to TSAG at the upcoming meeting,
7 - 11 November 2005, unless circumstances change.
5.4.3 The SG 19 Chairman encouraged participants to continue to strive for greater openness and
public accessibility for their documents within the agreed guidelines in order to obtain the fullest
possible experience in this area.

Systems Beyond IMT-2000, Q.FNAB, version 4.0 (Revision 1) (TD 217R2).

Reviewed, and agreed to the Work Programme for Q.1/19 that has changed the
timing for Q.FNAB from 4Q2005 to 3Q2006.
7.1.3
Q.1/19 proposed no outgoing liaison statements.
7.1.4
The agreed schedule of interim activities is included in §9 below.
7.2
Joint Q.2/19 “Mobility management” and Q.5 “Convergence of evolving IMT-2000
networks with evolving fixed networks”
7.2.1 The meeting reviewed and approved the report of the joint meetings of Q.2 and 5/19 in
TD 235R2, attached as Annex 6.
7.2.2
Key results extracted from the report of the joint meeting of Q.2 and 5/19 are:

Draft Q.MMR (Mobility Management Requirements; TD 232R1) was enhanced in
the areas of mobility management features and the requirements for inter-CN and
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC
-8COM 19 – R 3 PUBLIC – E
inter- and intra-AN mobility management. A requirement was added on support of
private IP address domains. Mobility definitions have been harmonized with Q.6/13.

Draft Q.MMF (Framework for Mobility Management; TD 233R1) was enhanced in
the areas of Location Update, Registration, Query and Reply. A new section was
added on Paging Management.

Draft Q.FMC stage 2 (IMS-based Fixed Mobile Convergence; TD 234R1) was
extended with new sections on high level principles and support for Voice Call
Continuity. An annex was added that provides an Enterprise Role Model as the basis
for identification of the prime inter-domain interfaces for FMC. The scope section
was updated to better reflect the intent of the recommendation to identify and refer to
suitable inter-domain interface specifications for IMS based FMC.

The mobility management and FMC related sections of the eighth FG NGN meeting
output documents were reviewed. A liaison response to the FG NGN was prepared.

After the discussion in the JRG of Q.6/13, Q.2/19, Q.5/19 on the allocation of FG
NGN deliverables (see TD 225R2) the joint Q.2 and 5/19 meeting confirmed its view
that FRMOB (Mobility Management Capability Requirements for NGN) and IFN
(IMS for NGN) fall wholly within the mandates of Q.2 and 5/19, respectively.
The UK expressed a reservation on the conclusion reached by the joint Q.2 and 5/19 meeting for the
named Focus Group deliverables that they fell wholly within the mandates of Q.2 and 5/19, in that
this does not reflect the scope and content of these documents.
7.2.3
The joint meeting of Q.2 and 5/19 proposed one outgoing liaison statement as noted in §10.
7.2.4
No interim activities are presently scheduled.
7.3
Q.3/19 “Identification of existing and evolving IMT-2000 systems”
7.3.1 The meeting reviewed and approved the report of Q.3/19 in TD 230R1, attached as
Annex 7.
7.3.2
The key result extracted from the report of Q.3/19 is:

Reviewed and approved inputs of TTA for Recommendation Q.1741.4 and prepared
this Recommendation for Consent.

FG NGN output document 224 draft FG NGN/IFM (IMS for Next Generation
Networks) was reviewed and is considered to be progressing appropriately.
7.3.3
Q.3/19 proposed one outgoing liaison statement as noted in §10.
7.3.4
No interim activities are presently scheduled.
7.4
Q.4/19 “Preparation of a handbook on IMT-2000”
7.4.1
The meeting reviewed and approved the report of Q.4/19 in TD 229, attached as Annex 8.
7.4.2
The key result extracted from the report of Q.4/19 is:

A new chapter on emergency communications was reviewed and adopted by the
meeting participants for the inclusion into the second Edition of Handbook on IMT2000.
7.4.3
Q.4/19 proposed one outgoing liaison statement as noted in §10.
7.4.4
No interim activities are presently scheduled.
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC
-9COM 19 – R 3 PUBLIC – E
7.4.5 The Rapporteur made a plea for measures to be taken to further encourage the involvement
of developing countries and countries with economies in transition in the work on Handbooks. Input
on the needs of such countries that can be addressed by the work on Handbooks has the potential to
be particularly beneficial in stimulating input.
7.5
Joint meeting of Q.6/13 “NGN mobility and fixed-mobile convergence” plus Q.2/19
“Mobility management” and Q.5/19 “Convergence of evolving IMT-2000 networks
with evolving fixed networks”
7.5.1 The meeting reviewed and approved the report of Q.5/19 in TD 225R2, attached as
Annex 9.
7.5.2
Key results extracted from the report of Q.5/19 are:

The meeting agreed there is no essential difference from a network perspective
between the long term objectives of the NGN and SBI2K frameworks with regard to
Mobility Management. FMC is an important aspect of both frameworks.

The meeting agreed that the FG NGN deliverable on NGN Functional Requirements
and Architecture (FRA) provides an overarching framework for NGN and should be
elaborated in association with Q.6/13 and Q.2/19 and Q.5/19.

There was a lot of support from Q.2/19 and Q.5/19 experts for the view that the FG
NGN deliverables on mobility (FRMOB) and IMS for Next Generation Networks
(IFN) are pertinent to the Q.2/19 deliverables on Mobility Management and Q.5/19
deliverable on IMS-based FMC respectively. Q.6/13 experts were of the opinion that
it was out of scope for the current meeting to agree on a recommending an allocation
of these deliverables, and proposed to leave it to the JCA and coordination between
SGs.
7.5.3
The joint meeting of Q.6/13, Q.2/19 and Q.5/19 proposed no outgoing liaison statements.
7.5.4
No interim activities are presently scheduled.
8.
Allocation of NGN deliverable responsibilities
8.1
TD 238 provided the most recent version available of the proposed allocation of FG NGN
deliverables into the regular study group structure. SG 19 noted that deliverables FRMOB and IFN
(see §§7.2.2 and 7.5.2 above) are marked as “still under review” with respect to which study group,
13 or 19, should be the approving study group. The SG 19 Chairman was given the mandate to take
the SG 19 position into the SG 13 closing plenary that these two deliverables fall within the
purview of SG 19 per WTSA-2004 discussions and decisions as captured in WTSA document 118
and Resolution 2 (the UK expressed a reservation on this and asked that this be indicated by the SG
19 Chairman when he raises this in the SG 13 plenary), and as “endorsed by a meeting between the
TSB Director and Heads of Delegation on 7 September and form the basis of the ongoing
coordination, planning and management of the NGN work.” (TD 240)
9.
Future meetings
9.1
The next meeting of SG 19 is scheduled to take place 23-27 January 2006 in Geneva per
TSB Circular 40 dated 25 July 2005, during the same period as SGs 13 and 11. Further details will
be provided by Collective Letter and will be posted on the SG 19 web site in the usual manner. At
this time, specific time allocations to Questions, including which Questions across which study
groups should meet together, were not available. The meeting agreed that the SG 19 Chairman
should take the position in the SG 13 closing plenary that this was an urgent area to be sorted out,
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC
- 10 COM 19 – R 3 PUBLIC – E
and that it should be addressed through correspondence amongst the leadership of the involved
study groups with the aim of having an agreed arrangement in place no later than the start of the
TSAG meeting, 7 - 11 November, 2005, and taking due account of the potential for conflicts with
other important meetings that are taking place around the same time. Further specifics will be
developed in consultation with the Rapporteurs.
9.2
The SG 19 Meeting Schedule Coordinator, Mr Motoshi Tamura, presented TD 201R1
which provides information on the schedule for selected meetings of other groups relevant to the
SG. This provides an excellent overview of meetings of interest to SG 19 and will also be used by
the SG leadership and Rapporteurs in planning meeting schedules as noted above. An update
reflecting SG electronic meetings and Rapporteurs’ meetings, etc., will be provided after the
meeting as TD 201R2. Mr Tamura’s efforts are much appreciated.
9.3
Subject to adjustments per the anticipated correspondence activity indicated above, it is
anticipated that the overall SG 19 meeting schedule for the 23-27 January 2006 meeting will be
similar to that used at the current meeting. SG 11 meets the same week. The SG 19 Chairman will
work with the SG 11 Chairman to avoid overlapping plenaries. The SG 11, 13 and 19 Chairmen
have agreed to run their closing plenaries sequentially on 27 January. These measures should assist
smaller delegations in tracking the activities of the three study groups meeting in parallel.
9.4
Interim meetings were proposed and approved as listed below. Electronic meetings will
take place using the electronic discussion board facilities at
http://forum.itu.int/jive/index.jspa?categoryID=2 supplemented by meeting document access on
TIES. Guidelines for the conduct of electronic meetings may be found at http://www.itu.int/ITUT/studygroups/templates/index.html.

9.5
Information on the arrangements for the above meeting will be made available on the
ITU-T SG 19 web page: http://www.itu.int/ITU-T/studygroups/com19/index.asp. Rapporteurs are
encouraged to send out reminders as they approach the dates for their meetings. The TSB will only
post information about the above meetings as provided by the Rapporteurs.
10.
Approval of outgoing liaison statements
10.1
The following table provides a list of the liaison statements that were proposed. All the
listed Liaison Statements were reviewed and approved during the presentation of the individual
Question reports except as noted in §10.2. The work of Mr Tamura in Mr Masambu’s absence in
coordinating these liaison statements is much appreciated.
10.2
In TD 112, received at the previous SG 19 meeting, TSAG requested that study groups
provide information on tracking outgoing LSs to non-ITU-T organizations. A report to TSAG on
this is provided in TD 241, included in the table below.

Annex 3 - SG 19’s Position on its Role in NGN Studies
Introduction
SG 19’s view on its mandate, on the handling of the transition of mobility and fixed/mobile
convergence studies, and on an approach to continuing to progress NGN studies is provided in this
document.
This text below was proposed to and agreed at the SG 19 opening plenary on 5 September. The UK
expressed a reservation on this text.
SG 19 Views on moving forward with NGN work
Per WTSA-2004 Resolution 2, SG 19 is:
“Responsible for studies relating to network aspects of mobile telecommunications networks,
including International Mobile Telecommunications 2000 (IMT-2000) and beyond, wireless
Internet, convergence of mobile and fixed networks, mobility management, mobile multimedia
functions, internetworking, interoperability and enhancements to existing ITU-T Recommendation
on IMT-2000.”
WTSA-2004 designated SG 19 as the “Lead study group on mobile telecommunication networks
and for mobility.”
SG 19 is one of the study groups charged with Next Generation Network studies. WTSA
Document 118 describes the relationships of relevant study groups to the work on NGN.
On the basis of the mandates assigned and the decisions taken at WTSA-2004, it is clear that SG 19
has a central role in mobility management studies and in studies addressing the convergence of
fixed and mobile networks.
SG 19 supports the continuation of the NGN JCA to deal with the policy and administrative aspects
associated with NGN studies.
With the transition of the work of the FG NGN into the regular study groups, there is an opportunity
to resolve issues in work allocation. SG 19 supports the continuation of a group with a mandate to
maintain a record of NGN tasks and how they fit in the overall NGN view, and which will assist in
scheduling joint meetings of Rapporteurs to progress the work efficiently and effectively. SG 19
recognizes the role of SG 13 wrt managing NGN studies and supports the work of Q.1/13 (Project
coordination and release planning for NGN) in this regard. The Study Group ownership of each
individual document should be clear from the onset and, as work progresses, there should be
collective agreement on the assigned ownership of documents. Ownership must respect assigned
mandates per WTSA-2004 Resolution 2.
SG 19 supports holding co-located meetings of NGN-related Questions at about the same frequency
as FG NGN meetings are presently held so that momentum can be maintained, and progress can be
continued and perhaps accelerated. During regular Study Group meetings (co-located SGs 11, 13
and 19), individual Questions which meet between Study Group meetings should also meet to
facilitate ongoing rapid progress, and ensure fairness and transparency so that the full membership
will have opportunity to supervise, review, and consent the deliverables.

The following provides a brief summary of the discussions on and dispositions of input documents
that were assigned to the work item “General Items.”
TD-115 (Response to SG19 Liaison Statement on Trial of Public Access to SG 19
Documentation) – TSAG endorses the Study Group 19 proposal in its liaison statement on “Trial
of Public Access to SG19 Documentation” with a number of amendments. TSAG agrees that how
to proceed further can be decided at the end of 2006. TSAG looks forward to hearing reports, which
include subjective aspects, regarding the effectiveness of this trial from Study Group 19. Noted.
TD-117 (LS to ITU-T Study Groups on work on Telecommunications for Disaster Relief and
Early Warning and an Action Plan) – TSAG D 9 proposed that more technical standards could be
created in support of Telecommunications for Disaster Relief (TDR) and Early Warning (EW). The
Action Plan as agreed at TSAG in its meeting 14-18 March 2005 is attached. TSAG encourages all
Study Groups to review their work programme for work in TDR/EW, as applicable and to provide
TSAG and Study Group 2 with a feedback. Noted.
TD-181 (Project Co-ordination and Release Planning for NGN) – Study Group 13 continues to
work on an interactive ITU-T Web site for NGN and to request each Study Group to provide details
of its existing Recommendations or Recommendations under development that would fit within the
scope of NGN. Study Group 13 also requests that each Study Group provide a single contact point
for NGN Release planning. In the discussion the group pointed out that Q.1702 and Q.1703 could
be relevant. But the group also pointed out that this information has already been sent to Study
Group 13 by TD 120 as a reply to the same request from Study Group 13 and agreed that any
further liaison statement is not needed at this moment.
TD-184 (Liaison statement on the first OCAF Focus Group deliverable, Carrier Grade Open
Environment (CGOE) reference model) – The objective of the Open Communications
Architecture Forum (OCAF) Focus Group under the Study Group 13 is to agree on specifications
for a set of components for a new carrier grade open platform that will accelerate deployment of
NGN infrastructure and services. Regarding its first deliverable “Carrier Grade Open Environment
(CGOE) reference model,” Study Groups are invited to comment, propose for enhancement, or
indicate interest. Noted.
TD-187 (Response to liaison on general security policy for secure mobile end-to-end data
communication) – Q.9/17 explains X.msec3 further in response to the liaison from Study Group
19. X.msec3 focuses on mobile environment and can support NGN evolution, since for value added
security service, conceptions and key techniques in X.msec3 can be applied to both fixed and
mobile environment. Noted.
TD-188 (Report of the 7th FGNGN meeting) – The 7th FGNGN meeting report and the current
draft of the NGN Release 1 scope document are attached for information. The Q.1/19 acting
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC
- 19 COM 19 – R 3 PUBLIC – E
Rapporteur pointed out that this temporary document is obsolete because TD 215 is now available.

TD-189 (Outputs from the 7th ITU-T NGN Focus Group meeting) – The NGN Release 1 scope
document and the NGN Release 1 requirement document as of the end of the 7th FGNGN meeting
are attached to this liaison statement. FGNGN acknowledges the lead role of Study Group 19 in
harmonizing mobility related concepts and terminology with other parts of the ITU-T and requests
guidance from Study Group 19 on mobility related issues. Noted.
TD-192 (Reply to LS on Work on Telecommunications for Disaster Relief and Early Warning
and an Action Plan) – In response to the request from TSAG that all ITU-T Study Groups are
expected to increase their activities for TDR and EW and that an ITU-T Action Plan for TDR and
EW is to be established, Study Group 16 provides TSAG and SG2 with a first feedback on the
actions taken and improvements suggested to the Action Plan. The current possible contribution to
the Action Plan from Study Group 16 is attached. Noted.
TD-193 (LS on Multimedia Service Mobility) – This liaison statement from Study Group 16
informs that Q.29/16 has started work on requirements with regard to the deployment of
Multimedia Service mobility within NGN. Study Group 16 requests Q.2/19, Q.5 and Q.6/13 to give
a feedback to Q.29/16 and to give its view about a common implementation of this issue. Noted.
TD-194 (LS on V.15x-series applicability to PSTN/ISDN emulation/simulation services) –
Q.11/16 has developed Recommendations that address the transport of voice band modems over IP
networks. Q.11/16 requests that, in the definition of access and PSTN/ISDN emulation/simulation
services in the NGN, Recommendations V.150.1, V.151, V.152 and T.38 (for facsimile) be
considered. Noted.
TD-195 (LS on ISUP/BICC enhancement for VED) – Q.16/16 is currently defining a “VED for
mobile networks”. ISUP/BICC should be enhanced to carry VED (Voice Enhancement Device)
related information. On the other hand, a contribution describing the relevant coding and procedures
has been presented to Q.3/11, but has been put on hold waiting for Study Group 19, as the lead
group for mobile, for the support of this work. Q.18/16 asks Study Group 19 to confirm the need to
enhance ISUP/BICC to carry VED related information. NTT DoCoMo commented that since
Q.1/19 is now discussing network architecture, that Q.1 is not in a relevant position to comment on
this topic. NTT DoCoMo further commented that this enhancement has possible impacts on existing
systems and that it needs to be carefully handled by Q.3 where experts of 3GPP/3GPP2 are
working.
TD-215 (Report of the 8th FGNGN meeting) – The 8th FGNGN meeting report and the current
draft of the NGN Release 1 scope document are attached for information. Since no comments were
raised from the floor, the Q.1/19 acting Rapporteur requested participants to take time and to look
through the documents. The document was revisited afterwards, but no comments were raised.
Noted.
TD-218 (Draft agenda for Q.1/19) – This temporary document is a draft agenda for Q.1/19.
TD 218 was revised into TD 218R1 by adding three documents to be handled. The group reviewed
and agreed to TD 218R1.
6.3
Functional Network Architecture for Systems Beyond IMT-2000 (Q.FNAB) (D 23;
TD 217)
Based on input contributions and discussions at the meeting, Q.FNAB version 4.0 (Revision 1) was
developed and made available as TD 217R2.
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC
- 20 COM 19 – R 3 PUBLIC – E
The Q.FNAB version 4.0 (Revision 1) is based on the Q.FNAB version 3.0 (TD 217) and the
modifications proposed by Delayed Contribution 23 (D 23) and the comments received during the
sessions of Q.1/19.
The following provides a brief summary of the discussions on and dispositions of input documents
that were assigned to the work item “Q.FNAB”.
D-23 (Network function for Q.FNAB) – This delayed contribution is from Korea.
< Discussion notes are in the version of this document behind TIES.>
TD-217 (Draft Recommendation Q.FNAB (version 3.0)) – This temporary document is the latest
version of Q.FNAB, which is the output from the last Study Group 19 meeting during 3-6 May
2005 and which was used as the base text for the current Q.1/19 sessions. After discussion of D 23,
the Q.FNAB version 4.0 (TD 217R1) was drafted. This was further reviewed and the Q.FNAB
version 4.0 (Revision 1) (TD 217R2) was drafted including comments that would clarify issues to
be solved. The Q.FNAB version 4.0 (Revision 1) (TD 217R2) was reviewed and agreed to.
6.4
Review of Work Programme for Planned Deliverables
Based on the comments received during the Q.1/19 meeting, Stage 2 Recommendation Q.FNAB
(Functional network architecture for systems beyond IMT 2000), version 4.0 (Revision 1), was
developed.
It was agreed that one electronic meeting should be held to progress the work on Q.FNAB before
the next SG 19 Meeting. The planned Q.1/19 Rapporteur’s Electronic Meeting is scheduled for 8-22
November 2005. And besides it was agreed that the timing for Q.FNAB should be 3Q2006 instead
of 4Q2005 due to the lack of maturity of the current Q.FNAB. The group pointed out that elements
of Q.FNAB, including the whole architecture, security functionalities, or service platform
functionalities are still missing and commented that Q.FNAB needs to be revisited to consider
consistency with NGN work. The detailed Work Programme for Q.FNAB is provided in Annex 1 to
TD 236R1.
6.5

management. A requirement was added on support of private IP address domains. Mobility
definitions have been harmonized with Q.6/13.

Draft Q.MMF (Framework for Mobility Management) was enhanced in the areas of
Location Update, Registration, Query and Reply. A new section was added on Paging
Management.

Draft Q.FMC stage 2 (IMS-based Fixed Mobile Convergence) was extended with new
sections on high level principles and support for Voice Call Continuity. An annex was
added that provides an Enterprise Role Model as the basis for identification of the prime
inter-domain interfaces for FMC. The scope section was updated to better reflect the intent
of the recommendation to identify and refer to suitable inter-domain interface specifications
for IMS based FMC.

The mobility management and FMC related sections of the 8th FGNGN meeting output
documents were reviewed. The results are contained in TD 237, the liaison response to the
FGNGN.

After the discussion in the JRG of Q.6/13, Q.2/19, Q.5/19 on the allocation of FGNGN
deliverables (see TD 225R2) the joint Q.2/19 and Q.5/19 meeting confirmed its view that
FRMOB (Mobility Management Capability Requirements for NGN) and IFN (IMS for
NGN) fall wholly within the mandates of Q.2/19 and Q.5/19 respectively.

thanked all delegates for their willingness to hold a joint meeting in the absence of the Q.2/19
Rapporteur.
6.2
Q.MMR
D 21 from Korea is titled “Revised Draft Text of Q.MMR”.
< Discussion notes are in the version of this document behind TIES.>
D.28 (Korea Telecom) was directed at Q.MMF, but in the ensuing discussion it was agreed to
incorporate the requirement to allow for use of private IP addresses in Q.MMR.
During the review of Q.MMR it was noted that the following areas need further work:

the requirement to support other forms of mobility than just terminal (MT) mobility is not
yet reflected throughout the document

requirements on MM to be able to take QoS constraints into account

specific aspects of service mobility, such as requirements on the domains from where
service may be delivered (home, visited network)
This last point was brought out by TD 193 (Q.29/16).
ITU-T\COM-T\COM19\R\R3E-PUBLIC.DOC
- 23 COM 19 – R 3 PUBLIC – E
It was agreed to include appropriate editor’s notes into the next draft. Contributions on these

< Discussion notes are in the version of this document behind TIES.>
D 28 (Korea Telecom) proposes to allow for use of private IP addresses and to reflect in section 5
of Q.MMF that an IP address itself may be used as a User ID. It was agreed to incorporate the first
proposal as a requirement in Q.MMR and the proposed procedures in Annex A of Q.MMF on MIP.
The second proposal was also accepted.
During the review of Q.MMF it was noted that it also lacks a description of the support for other
forms of mobility such as network mobility. It was agreed to include an appropriate editor’s note
into the next draft. Contributions are requested.

Organization of Meeting
This is the report of the Joint Rapporteurs’ Group meeting of Q.6/13, Q.2 and 5/19 that was held for
three quarter day sessions on 5 and 7 September 2005. The meeting was chaired by Felix Zhang,
Q.6/13 Rapporteur and Kees den Hollander, Q.5/19 Rapporteur. The latter was also representing the
Q.2/19 Rapporteur who was unable to attend the meeting.
The meeting agenda was published in TD 45 (WP2/13) and TD 216 (GEN/19). It is reproduced in
Annex 1 to TD 225R2.
The meeting was attended by about 35 participants.
2.
Key results
The meeting agreed there is no essential difference from a network perspective between the long
term objectives of the NGN and SBI2K frameworks with regard to Mobility Management. FMC is
an important aspect of both frameworks.
The meeting agreed that the FGNGN deliverable on NGN Functional Requirements and
Architecture (FRA) provides an overarching framework for NGN and should be elaborated in
association with Q.6/13 and Q.2 and 5/19.
There was a lot of support from Q.2 and 5/19 experts for the view that the FGNGN deliverables on
mobility (FRMOB) and IMS for Next Generation Networks (IFN) are pertinent to the Q.2/19
deliverables on Mobility Management and Q.5 deliverable on IMS-based FMC respectively. Q.6/13
experts were of the opinion that it was out of scope for the current meeting to agree on a
recommendation for the allocation of these deliverables, and proposed to leave it to the JCA and
coordination between SGs.

Report of discussions
4.1
Introduction of FGNGN output documents
The meeting considered the relevant sections of FGNGN-MR-00056, the FGNGN Chairman’s
report of the last meeting held in Geneva (24 August – 2 September, 2005). With regard to the
request to review NGN terminology, it was agreed to consider the mobility related terminology in
detail during the Joint Q.2 and 5/19 meeting.
The introduction of FGNGN-OD-00223 (NGN Functional Requirements and Architecture) raised
the question if the Q.2/19 Mobility Management Framework (Q.MMF) can be easily mapped on
FRA. It was confirmed that Q.MMF complies with the requirement for independence between
Transport and Service Strata, but a detailed mapping on FRA functional entities needs further study.
FGNGN-OD-00225 (Mobility Management Capability Requirements for NGN) was introduced.

authentication. The Rapporteur for Q.5/19 gave an overview of the contributions to this meeting to
further the work on Q.FMC stage 2. This covers D.18, D.17 and D.19.
< Discussion notes are in the version of this document behind TIES.>
In the last session of this JRG meeting the Q.5/19 Rapporteur informed the meeting of the
enhancements to Q.FMCstage2 that were agreed at the meeting.

Work allocation and plan
Based on the review of the most relevant FGNGN draft deliverables on the one hand and the work
in progress under Q.6/13, Q.2 and 5/19 on the other, the Q.5/19 Rapporteur explored the possibility
to come to a consensus view on the most desirable allocation of the prime responsibility for these
FGNGN deliverables. This based on the strong desire from SG19 from a process perspective to
have the prime responsibility for each NGN deliverable assigned to a single question.
It was agreed that it is critical to align the architecture work under our questions with the NGN
framework architecture and that Q.6/13, Q.2 and 5/19 should therefore be associated with this work.
Strong views were expressed by SG19 participants that Qs.2 and 5/19 would be the appropriate
prime questions for the FRMOB and IFN documents respectively, also in light of the SG19
mandate. Q.6/13 participants were however of the opinion that the allocation of FGNGN
deliverables is out of scope for a JRG meeting, and hence no consensus could be reached.
All delegates shared the view that there is no essential difference from a network perspective
between the long term objectives of the NGN and SBI2K frameworks from a Mobility Management

perspective. FMC is an important aspect of both frameworks. For this reason it is desirable to
continue with JRG meetings to co-ordinate the work and avoid overlap of work
4.7
Co-ordination of work at the January 2006 SG 13 and SG19 meeting
The WP2/SG13 chairman informed the meeting that no decisions had been reached yet by the JCA
on the allocation of FGNGN deliverables and co-ordination of work between NGN related
Questions. It is therefore not possible to firm up plans for JRG meetings in January.
Concerns were expressed about the current mode of operation, where JRG meetings do not have to
reach agreements for the work under the participating Questions to proceed. The Q.5/19 Rapporteur
expressed his preference for a JRG to have well defined deliverables that are progressed in JRG
meetings and not anywhere else.
The Rapporteurs will again request joint sessions of Q.6/13, Q.2 and 5/19 early on in the
proceedings in order to have contributions of common interest reviewed only once. Detailed
planning will have to wait until guidance is received on the organization of the work on NGN
related questions.
